OpenAI Ads API Key Guide for Advertisers (2026)

The Advertiser API key unlocks reporting, attribution, and campaign automation for ChatGPT Ads — but it is not the same key as the OpenAI API. Here is how to get it, secure it, and use it.

Short answer: open Ads Manager → Settings, create an Advertiser API key, save the secret once. Use it for reporting dashboards and automation — never in public code. It is separate from the OpenAI API key at platform.openai.com.

Ads API Key vs OpenAI API Key

	Advertiser API key	OpenAI API key
Created in	Ads Manager → Settings	platform.openai.com
Controls	Ad account, campaigns, insights	Models, assistants, embeddings
Billing	Ad spend account	API usage account
Use with	ChatGPT Ads Monitor, reporting scripts	Chatbots, automations, apps

Get Your Key in 4 Steps

Create a new Advertiser API key. Give it a clear name like "reporting-dashboard".

Copy the full secret immediately — it shows only once. Store it in a password manager or server secret.

Paste it into a trusted tool (like our Monitor) or your reporting script. Never commit it to git or frontend code.

What You Can Build With It

Reporting dashboards — spend, delivery, 30-day click vs 1-day view attribution, platform splits. Try it live: ChatGPT Ads Monitor (key never stored).

Account audits — validate billing, pixel health, and brand-review readiness: Account Inspector.

Automation — pause losers, shift budgets, sync reports to sheets. Keep keys server-side with rotation.

Key Safety Rules

→ One key per integration, named clearly, so a leak is traceable.

→ Prefer read-only scopes where available; least privilege always.

→ Leaked? Revoke in Settings immediately, issue a replacement, update integrations.

→ Never paste keys into AI chats, screenshots, tickets, or shared docs.

Frequently Asked Questions

Where do I find my OpenAI Ads API key?

In Ads Manager, open Settings and create an Advertiser API key. The full secret shows once — save it immediately in a password manager or server secret store.

Is the Ads API key the same as the OpenAI API key?

No. The OpenAI API key (platform.openai.com) is for models. The Advertiser API key (ads.openai.com → Settings) is for ad accounts, campaigns, and reporting. Different dashboards, different billing.

Can I paste my key into a reporting dashboard?

Only into tools you trust, over HTTPS, ideally with a dedicated read-only key. The key should never appear in public code, screenshots, or shared documents.

What can I build with the Ads API key?

Campaign management, delivery and spend reporting, click/view attribution splits, platform breakdowns, product-feed reporting, and conversion insights.

What should I do if my key leaks?

Revoke it immediately in Ads Manager → Settings, create a replacement, and update every integration. Treat a leaked key as compromised.
